WebAug 8, 2024 · In nature, male sterility appears in plants in many different forms. It was broadly classified on the basis of phenotype and genotype [ 8 ]. Phenotypic male sterility can be structural, sporogenous and functional male sterility (Fig. 1 ). Structural male sterility arises because of anomalies in male sex organs [ 8 ]. WebOf the three types of male sterility mentioned, pollen sterility is by far the most common and the only one that has played a major role in plant breeding and hybrid seed production.
